问题

最近开发能力开放平台，需要将Dubbo服务转换成Rest服务，虽然转换很成功(后续文档会写出如何将Dubbo服务转换成Rest接口)，但是调试起来特别的麻烦。

解决方案：

Fiddler解决方案：

下载Fiddler，然后只需要添加一小段代码就能进行调试了：

#能力开放平台系列-Fiddler访问Rest服务

Java代码解决方案

然后想到用Java代码去访问。首先将下列代码添加到build.gradle中

compile 'org.apache.httpcomponents:httpclient:4.5'

代码如下：

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.ContentType;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClients;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.net.URISyntaxException;

import java.net.URL;

import java.util.Map;

public class HttpClientUtil {

    private static final Log logger = LogFactory.getLog(HttpClientUtil.class);

    public static String sendPostRequest(String url, String data) throws IOException,

            URISyntaxException {

        CloseableHttpClient httpclient = HttpClients.createDefault();

        HttpPost httpPost = new HttpPost(new URL(url).toURI());

        StringEntity dataEntity = new StringEntity(data, ContentType.APPLICATION_JSON);

        httpPost.setEntity(dataEntity);

        CloseableHttpResponse response = httpclient.execute(httpPost);

        try {

            if (response.getStatusLine().getStatusCode() == 200) {

                HttpEntity entity = response.getEntity();

                BufferedReader reader = new BufferedReader(new InputStreamReader(

                        entity.getContent()));

                StringBuffer buffer = new StringBuffer();

                String tempStr;

                while ((tempStr = reader.readLine()) != null)

                    buffer.append(tempStr);

                return buffer.toString();

            } else {

                throw new RuntimeException("error code " + response.getStatusLine().getStatusCode()

                        + ":" + response.getStatusLine().getReasonPhrase());

            }

        } finally {

            response.close();

            httpclient.close();

        }

    }

    public static void main(String[] args) throws IOException, URISyntaxException {

        String result = HttpClientUtil.sendPostRequest(

                "http://10.1.50.81:20880/xxx/xxx/xxx", "{\"count\":1}");

        System.out.println("++++++++++++  " + result);

    }

}
